wi e-w communion Application fiiean 5,. 9 astea m 449,991] r I This invention relates toia window construction of that type including; a vertically adjustable lower and uppersash, andhas for its object to provide, in a manners-S here: ll ina'fter set forth, a windowso constructed and arranged to eliminate the employment of sash weights, sashcords and pulleys for retaining a sash in position when adjusted from normal. 7 v

The invention further aims to provide, in a manner as hereinafter set forth, a means other than sash cords, sash weights and pulleys for holding the sash or sashes of a window'in position when adjusted'from normal and with such means so constructed and arranged to provide a weather strip to exclude air, dust and moisture.

A furtherT'obj set of the invention is to provide, in-a manner as hereinafter set forth, 'a window construction including sashes and guide strips for the latter, and with'the guide stripsso constructed andarranged to provide a loose fit between them and the sashes whereby the sticking of the latter-due to is preventeda V A A further ob ect of the nventlon 18, to provide, in a manner as hereinafter set forth, a

window structure including means to provide a complete insulation around the frame to prevent leakage and thereby overcoming leakage through'the commonly used sash weight boxes. i I i I A further object of the invention is to pro}- vide, in a manner as'hereinafter 'set forth, a windowconstruction to provide a complete insulation aro undthe frame and further for retaining the sash orsashes in adjusted position without the employment of sashweights, sash cords and pulleys. I

A further object'of the invention istoprovide, in ama'nner as hereinafter set forth, a window construction includingmeans to' set up a complete insulation around the frame and which can easily be applied and of a form to occupy minimum space.

7 Further objects of the invention are to provide, in a manner as hereinafter set forth, a window constructlon for'the purpose re ferred to which is simple in its construction warping or by collectionof paint and-varnish and arrangement, strong, durable, compact, thoroughly efiicient in its use, readily assembled, and comparatively inexpensiveto man 'ufacture. 7 1 i ETWiththe foregoing and other objects in view the invention consists'of the novel construction, combination and arrangementof parts ashereinafter more specifically described, and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can lac-resorted to which fall within the scope of the claims hereunto appended. j

Figure 7 is a fragmentary view in perspective of the guide strip. Referring to the drawings, the window frame is generally'indicated at 1 and the lat- $5 ter has-each side 2 thereof provided centrally of its inner face with a parting groove 3 of the desired depth. The groove 3 extends from the top frameinember tothe bottom frame member or sill of the window frame. 99 The'top frame member is indicated at 4 and the sill at 5. The front and rear of the win dow frame have means indicatedat 6,7 respectively' for. confining. in connection with the guide strips 8, 9 the lower and upper sashes 10,11 respectively within the framel. The side stiles 12 of. the sashes are spaced from the inner faces j of the side members 2 of the frame 1. The meansindicated at 6, 7

function as guides. Thesaid means 6, 7 are 100 1 member is of a depth less than the depth of V 18, 19 of the casing member. The purpose of ferred to generally at 13, '14: and each is positioned Within a groove 3 and flanged'to abut against the inner face of aside member=2of the window frame. The body of each casing the grooves. As the casing members 13, 1a are of like .constructiombut one will be de'- scribed as the description ofonewill-apply Y to the other. Each casing memberzcorre- I side member 2 of the window-frame bordersponds in length to the length ofthe'groove in which it is mounted; Each casingmember includes an inner wall 15, a pair of side walls 16,17 andapair of oppositelyextending flanges 18, 19' which are disposed at right angles with the outer ends of the side walls 16, 17 respectively. -The inner part of each side wall is inset toprovide a curved part 20 and a straight part 21, the latter merging intothe inner wall 15 and the width of said innerwall is less thanthe width at the open end of the member. The inset parts of the side walls 16, 17 are'oppositelydisposed. The casing memberis of channel-shaped cross section'and has its inner wall 15 providedwith a set of lengthwise extending, oval-shaped slots 22. Theinnerwall 15 and side walls 16,

v 17 provide the body portion of the casing and which isdisposed within theg'roove 3 andwith the flanges 18, 19 of thecasing positioned against the grooved. inner face of a ingthe sides of the groove3. .When the cas- 1ng member, is arranged in groove .3'the inner wall 15 thereof is arranged in spaced relation with respect to the inner wall of the'groove and the outer parts of the sidewalls 16, 17 abut against the side walls of groove 3.

The width ofthe body portionof-the .cas-

ing member is such that the outer parts of the side Walls 16, 17 will. snugly'engage the side Walls of the groove 3. n

The Window construction includes a'pair of oppositelydisposed holder-members of channel-shaped cross section.- Each holder member isof a length corresponding to the length of the casingjmeinber. The holder members are generally indicated. at 23, 24 and are of like construction, therefore but one holder member will be described as the description of one will apply to the other. Eachholder member includes a body portion formed of an inner wall 25, a pair of side walls-26, 27 and a pair of oppositely extendingfl'anges 28, 29 disposed at right angles to and formed integralwith theout'er ends of the side walls 26, 27 respectively. The inner wall'25: of the holder member is provided with andthe sides of the window frame.

The flanges 28 29 of' the'holder member oppose the flanges the holder member will be presently referred The guidestrips- 8, 9areof channel-shaped cross sectionan'd oppositely disposed with respect to each other. A; guidestrip is extended in and projects from the open end of a-holder member. As the guide strips are of like construction, but one will bedescribed, as the description of one will apply to the other. Each guide strip is open'at its rear. Each guide strip includes an'outer wall 31, apair of side walls 32, 33, and each of said walls is formed with an inner part 34, an intermediate part 35 and an outer part 36. The intermediate part 35 extends inwardly at right anglesfrom the outer part 36 andnierges into the, inner part 34 whereby the latter is inset. with respect to part 36. The intermediate part 35 provides seats for a purpose to be presently referred to. The parts 34: are extended into a holdermembe'r and snugly engages with the side walls of the latter. The parts 35 seat against the flanges of the holder member and the parts 36 are arranged exteriorly.oftheholder member. The parts 36inconnection withthe wall31 is positioned.

A guide strip is carried by a holder member and bodily moves withthe latter, as each holder member posed fianges on said'members will be interposed between a side stile of the sashes 10, 11 and a side member of the window 'frame.
